The omp2 Gene of HPS-type Bacteria Cloning and Sequence Analysis Isolates from Sichuan Province
Abstract: In order to compare the homology and antigen of Haemophilus parasuis (HPS)4 outer membrane protein P2(omp2), we design a test with specific primers, using PCR amplification of isolates of Haemophilus parasuis from Sichuan Province(HP Sch2010), ompP2 gene will be cloned into the pGM-T vector, and transformed into E. coli DH5α. Identified by PCR and sequencing and analysis, the sequencing results showed that the published 4 HPS SW124 strains omp2 gene (1077bp), compared with the amplified 1086bp purpose fragment(containing omp2 genes), is relatively stable, with the nucleotide homology level 97% and amino acid homology level of 92.5%. The variable regions are mainly concentrated in the three base sequences: 40-65,110-156,180-202.
